QTM216-16.000MDE-T

Overview

The QTM216-16.000MDE-T is a surface-mount CMOS oscillator manufactured by QST, housed in a compact 4-SMD, No Lead package measuring 2.0mm x 1.6mm with a height of 0.75mm. It operates at a fixed frequency of 16MHz and supports a supply voltage of 1.8V. The device features an Enable/Disable function and delivers a frequency stability of ±50ppm across an operating temperature range of -40°C to +85°C.

Feature Summary

• Compact 2016 SMD ceramic package designed for space-constrained applications
• Integrated enable/disable control via Pin 1 for power management
• CMOS output compatible with standard digital logic interfaces
• Wide supply voltage tolerance supporting system flexibility

Applications

• Smartwatch and wearable device clock sources
• System-in-Package (SiP) modules requiring low profile components
• Bluetooth Low Energy (BLE) communication interfaces
• Portable consumer electronics with strict size limitations

Procurement Notes

Verify the specific suffix 'D' in the part number against official QST documentation to confirm the exact supply voltage and enable/disable configuration. Ensure the selected variant matches the target system's voltage requirements and thermal specifications. Cross-reference the manufacturer datasheet for precise pinout definitions and recommended soldering profiles to guarantee reliable assembly and long-term operational stability.

Selection Notes

Select this component when a 16MHz clock signal is required within a 2.0x1.6mm footprint. The ±50ppm stability suits general-purpose timing needs rather than high-precision synchronization. Confirm that the 1.8V supply aligns with the host processor's I/O levels. Consider the enable/disable feature if dynamic power saving is necessary during idle states in battery-operated devices.

Part Context

This model belongs to the QTM216 series of low-profile CMOS oscillators from QST. The series utilizes SMD ceramic seam-welded packaging to ensure environmental robustness. Variants within the family differ primarily in frequency, supply voltage, and stability grades, allowing designers to choose based on specific bandwidth and accuracy constraints while maintaining a consistent mechanical form factor.

Replacement Considerations

Direct substitutes include other 2016 package CMOS oscillators from manufacturers like TXC or Epson, provided they match the 16MHz frequency, 1.8V supply, and ±50ppm stability. Verify pin compatibility and electrical characteristics before swapping to avoid redesigning the PCB layout or adjusting peripheral circuitry.
